VIDIOC_G_CHIP_IDENT improves debugging of card problems: it can be used to detect which chips are on the board and based on that information selected register dumps can be made, making it easy to debug complicated media chips containing tens or hundreds of registers. This ioctl replaces the internal VIDIOC_INT_G_CHIP_IDENT ioctl. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
